Lenscare moves depth of field and out of focus generation to post production. If you need high quality camera blurs with the flexibility of 2d post processing, Lenscare is a great choice. It can get you rid of long extra 3d rendering times. The key aspect during the development of these filters was to match the real thing as good as possible. Lenscare is available as plugins for Adobe After Effects and Photoshop compatible programs.
